We describe the use and distributed implementation of a functional language based on the graph‐reduction concept. Attention is given to the issue of implementing higher‐order functions and concurrent evaluation. Prospects for optimization of this implementation are pointed out.

Convergence and user-centricity are the leading trends in telecom network. The service creation scheme is changing to realize these trends. This paper describes the end-user driven service creation method for converged service over telecom and Internet domain. The proposed SCE fulfills the general SCE requirements and also comes up with the network trend to user-centricity and the network evolution towards convergence. The advantage of our approach comes from web based service creation and execution environment to satisfy end-user's requirements and encourage user's participation. Using our SCE, end-users can create their own service applications and use them anytime and anywhere through their personal devices.

In the improvement of robotic manipulator systems, open software platforms play an important role in control design of robots, especially where new techniques, as force control, want to be included. A good platform can provide both simulation functions that speed up the development of different algorithms and experimentation functions which include complex programming and huge data collection. This paper presents a new open software architecture for an industrial manipulator that permits easy implementation of model-based and sensor-based control concepts. In addition, it proves to be interesting for robotics research since it allows the integration of standard industrial components. The entire system has been successfully developed, implemented, and demonstrated for a robotic task which required the interaction between the manipulator and an unknown environment.

The present issue is composed of three contributed articles. In "Compilation of extended recursion in call-by-value functional languages," Tom Hirschowitz, Xavier Leroy and J.B. Wells formalize a compilation scheme mapping a functional language with generalized mutual recursion to a lower-level functional language with explicit heap and locations that enables in-place updates. In "Expressible sharing for functional circuit description," Matthew Naylor and Colin Runciman present an elegant solution to the problem of expressing data-structure sharing in a pure functional language.
